I just re-read the 3rd paragraph, and I think I missed the “then” in “which then signals” on the first reading. It’s fine as is. Thanks!

It seems like paragraph 2 is talking more about local APIs (at least, I see that was mentioned in the text in version 17 but not in 18), but paragraph 3 uses an example of a signal from a server.
